There are several ways to protect data in the front-end:
- Input validation: Ensure that any data input by users is in the correct format and does not contain any harmful code.
- Encryption: Use encryption to protect sensitive data, such as passwords, before it is sent to the server.
- Token-based authentication: Use tokens to authenticate users, rather than storing their passwords in plain text in a cookie or local storage.
- Content Security Policy (CSP): A CSP is a security feature that helps to mitigate the risks of cross-site scripting (XSS) and other code injection attacks.
- Use HTTPS: Use HTTPS to encrypt the communication between the client and the server to prevent eavesdropping and tampering.
- Keep software updated: Use the latest version of web browsers and front-end libraries to ensure that you have the latest security fixes.
- Use security library: Use security libraries such as helmet.js, cors, etc to protect your application from common vulnerabilities.
It is important to note that security is an ongoing process and it is important to stay informed about the latest threats and vulnerabilities, and update your security measures accordingly.
There are several ways to prevent data in a disabled field from being edited using the browser’s developer tools (such as the “Inspect” feature):
- Use a readonly attribute instead of disabling the field: By using the readonly attribute instead of the disabled attribute, the field will still be visible and will not be editable.
- Use JavaScript to disable the field: By disabling the field using JavaScript, it will not be possible to re-enable it using the browser’s developer tools.
- Use server-side validation: Ensure that any data submitted from the form is validated on the server, and reject any submissions that contain invalid data.
- Use a CAPTCHA: Implement a CAPTCHA to ensure that the form is being submitted by a human and not by an automated script.
- Use browser extensions: Use browser extensions such as NoScript, uMatrix, ScriptSafe etc to block malicious scripts running on the client-side.
- Use browser DevTools protection: Use browser DevTools protection feature to protect your application from malicious attacks
It is important to note that these methods can be bypassed by determined attackers, and it is important to use multiple layers of security to protect sensitive data. Additionally, it is important to stay informed about the latest threats and vulnerabilities and update your security measures accordingly.
